NAM is a military-themed first-person shooter that uses the Build engine. The protagonist has to fight his way through the jungle, with various weapons such as M16, M60, M79, LAW, and others. The missions range from urban gun battles to sneaking in the thick jungles and man-made tunnels under the ground. The battlefields are frequented by air strikes, anti-personnel mines (which the player can spot with a mine detector), fire fights, ambushes, snipers and tanks. Fellow soldiers will aid Alan in battle, though for the most part he'll have to depend on himself.
